For decades, Chinese brothers Gao Zhen and Gao Qiang have made a name for themselves with sculptures like this: irreverent contemporary artworks that skewer the authoritarian past, and present, of their native homeland. The "Execution of Christ" was exhibited in 2009. So too was "Mao's Guilt": a life-sized replica of the so-called supreme leader kneeling in a pose of solemn contrition.
But it was only 15 years later that such works, satirising one of China's most contentious idols, cost Gao Zhen his freedom.
